Inheritance of Genes

Sometimes townies have dyed hair. If you want to be really sure of their hair color, you have to check them in SIMPE.
That's the only sure way to make sure what their hair color really is.
I checked TS2Enhancer and the mom's hair is not only black, but genetically her mother and father's hair color were black too. There is no one further back in the family tree because the mom is a townie and the dad is a CAS sim.

From what I know, the inheriting of facial characteristics does not depend on the gender of the child, but rather which features each parent has labelled dominant. A dominant feature has something like a 60% chance of being passed on. With each sim, the chances of a feature being labelled dominant or recessive depends on their gender, yes. So, a female sim has a higher chance of her eyes being dominant, for example. So, she has a higher chance of passing on her eye shape to her kids, either male or female.
Finally I am getting the answer I need. How about the rest of the features such as jaw shape, ear, lips etc? Where did you get the above info from? Where can I find out more? Thanks!
Even so, 60/40 is for all intents and purposes not a whole hell of a lot different than 50/50. I do remember the 60/40 ratio though. I don't recall where I read it. The Prima Guide (for the original game) maybe? I'm not sure if it's possible to alter the ratio, or change how a particular feature is marked dominant and I wouldn't even know where to look for it in SimPE.
Again, if you try using the create a baby tool in the CAS it's all pretty randomish with features. It just doesn't seem as cut and dry as the hair and eyes are. It could well be 60/40, but 60/40 is pretty close to random anyhow.

I noticed that quite a few of the new OFB townies had totally different genetics to what they were presenting in game (so I changed them). Even Gilbert Jacquet is genetically blond, not black, so I changed him as well. I really don't know why they do this, it seems to pointless. The only reason I can think of is, as I've suggested before, so they will have stupido players who haven't even heard of SimPE, go "Ooh, I SAY, how did two black-haired parents get a red-haired child? Townies must have grandparents after all!" or something along those lines. In fact, I actually did read a thread like this once on the official BBS, where someone was insisting that townies had grandparents you couldn't see.

Yes, the genetics of the facial characteristics are confusing. I used to be under the impression that once a certain feature, say, and eye shape, is labelled dominant, it stays dominant throughout the generations (that's what it says in the guide... ). But then I noticed that when Brandi had her third son, a male clone of herself, his listed dominant facial features differed from hers. So, apparently, the dominance of each feature is reassigned for each sim, and an eye shape that got inherited as dominant may turn recessive, and so on.
I just checked the guide on this. (Keeping in mind that the guide has inaccrurate information on some other genetics issues) it says that, when a sim is made in CAS, each region of the face is randomly labeled dominant or recessive, but the chances of a certain feature to be labeled dominant depends on the gender of the sim. A male sim has a 66% chance of his brow, nose or jaw being labeled dominant, and "only" a 50% chance with eyes and mouth. Vice versa for females (but there are more features listed in the DNA in SimPE than these five mentioned, so it's incorrect at least in that regard).
About the chances of the features being passed on, the guide says that if one parent has a dominant feature while another recessive the child has a 66% chance of inheriting the dominant one. When both are dominant or recessive, then the chances are 50/50.
But, considering how correct the guide has been on some other issues, I wouldn't count on this information.

Makes you want to run head first into a brick wall, doesn't it? Grandparents you can't see .... mutter mutter

Well, that kind of makes sense. Men have more prominant brow ridges than women, and less gracile jaws (on the whole). Maybe what it is, is that when a man passes on his distinctive jaw (dominant) to his daughter, it then becomes a recessive feature because she's a female. I didn't know the facial features were supposed to be linked to gender and genetics. I thought the children just got a mix.
